摘要
目的 探讨 1.5T MRI技术在肛瘘(AF)术前的应用价值.方法 选取 92 例肛瘘患者,根据不同的检查方式,分为观察组(52 例)和对照组(40 例).两组患者均接受肛瘘切开术及围术期相关治疗,术前对照组采用探针探查,观察组采用 1.5T MRI技术.以手术结果为金标准,比较两组患者术前检出率情况(内口、主瘘管、支瘘管及囊肿)、Parks肛瘘分型准确率以及术后治愈情况(愈合时间、治愈率).结果 观察组内口、主瘘管和支瘘管及囊肿等术前检查检出率高于对照组,差异有统计学意义(χ2=4.817、5.904、14.775,P<0.05);观察组肛瘘分型准确率为 78.85%高于对照组的50.00%,差异有统计学意义(P<0.05);观察组的愈合时间短于对照组(t=9.050,P<0.05),观察组治愈率(80.77%)与对照组治愈率(77.50%)相比差异无统计学意义(P>0.05).结论 术前采用 1.5T MR技术可提高检测AF患者内口位置、瘘管数目和类型的准确率,缩短肛瘘患者术后愈合时间.
Abstract
Objective To explore preoperative application value of 1.5T high-field magnetic resonance in anal fistula.Meth-ods According to different examination methods,92 patients with anal fistula were divided into observation group(52 cases)and control group(40 cases).All patients underwent anal fistulotomy and perioperative treatment.Before surgery,control group was given probing,while observation group was given 1.5T high-field magnetic resonance.Taking surgical results as the golden standard,preoperative detection rates(internal orifice,main and lateral fistulas,cyst),accuracy rates of Parks anal fistula clas-sifications and postoperative cure(healing time,cure rate)in the two groups were compared.Results The preoperative detec-tion rates of internal orifice,main and lateral fistulas,and cyst in observation group were higher than those in control group(χ2=4.817,5.904,14.775,P<0.05),accuracy rate of anal fistula classifications was higher than that in control group(78.85%vs 50.00%,P<0.05),and healing time was shorter than that in control group(t=9.050,P<0.05).There was no significant differ-ence in cure rate between observation group and control group(80.77%vs 77.50%P<0.05).Conclusion The preoperative ap-plication of 1.5T high-field magnetic resonance can increase detection accuracy rates of internal orifice site,fistula number and types,and shorten postoperative healing time in patients with anal fistula.
